This invention relates to car iioor and v draft gear construction, being particularly adapted and advantageous for mine cars.

l factured, installed r A principal object of the invention is to a simple, rugged construction,

provide be easily and inexpensively manuwhich can lparts can be easil duplicated and replaced. The drawings sliow the invention applied to a conventional mine car mainly of wooden construction, with la 'plank fiooring 10, side 11, and end 12. As shown in Fig. 1, the car wheel 13 trenches somewhatfon the thickness of the'floorplO, which accordingly has an opening to accommodate it, with a sheet metal hood 14. Intothe'floor 1G is set or built a longitudinal center sill 15 of `channel cross section. At its'lower edges, this channel. 15 Vhas outward projecting lat; eral flanges 16 which are gained linto vthe adjacent planking and secured theretoby bolts 17. In the present instance, 'the channel corresponds in vertical depth substantially to' the thickness of the 'planking 10, so that itsupper surface is flush with that of the rest of the floor. Contributing to the support of the floor 10, along either side. of the opening of the channel 15, are

0 longitudinal sill angles .18, v.18, each` arranged with one of itsvflanges horizontal and the other depending vertically. As shown in Figs. 2 and 3, the horizontal angle and repaired, and whose- 15, 192s. serial No. 154,954.

3). The verticalangle flanges form downward extensions of the channel sides. As shown in Figs. 1, 2 and .3, there is a transverse tie strap 20 beneath the flooring 1K0 at the end thereof. This is secured to the `flooring 10 by bolts 21. .As shown in Fig. 1, this strap 20 extends clear across the floor and vup outside the car sides to their tops, where its ends are bent inward. In the mid-region of the floor, the strap 20 is offsetdownward under the ends of the angle sills 18 as bestvshown in Fig. 3.

The draft gear or drawhead shown 'in Figs. 1-3 is of a spring buffer type, comprising a double acting helical compression spring 24 in a rectan lar metal box 25 open at its bottom, an a coupler 26 with a broad head 27 adapted to take the cou- .pling link 28 and vcoupling pin 29, and also to serve as a buffer. The box 25 is mounted in the channel 15 and extends downward between the draft sill angles 18, y

and it is secured to `the channel sides and to the vertical'l angle lianges by rivets 31. The shank of the coupler 26 extends out between the channel sides and the'angles 18, 18. As shown in Figs. 1-3, the coupler 26 .is supported by a U-shaped carry-iron yoke 32, whose sides areseciired to the'chan- 25, each sleeve with its ange seated inside the box so as to afford a fixed abutment. for the spring 24 against inward movement of the other sleeve. Fortransmittin impacts, the coupler shank 26 bears direct y against the adjacent sleeve. 35; `for transmltting pulls, the coupler is connected to 'the other sleeve 3 5 by a bolt 36 extending through both sleeves as well as through the midst of the spring 24 between' them. The bolt head 37 bear against an internal shoulder 38 in the hollow coupler shank 26. The nut 39 on the other end of the bolt is secured by a cotter 40.

The construction shown in Figs. 4-6 differs from that of Figs. 1.3 in that builing shocks are taken by outward extensions of the car flooring at either side of the sills 15,18, 18 and of the draft gear. These are provided with angular protective sheathing 41 extending down outside a filler 42 bolted to the lower side of the plankingv at 42a. The carry-iron of Figs.. 1-3 is omitted. The binder' strap 2Oa is interrupted at either side of the vertical s1ll flanges, arid its ends are secured by the bolts .42a through the latter.

The draft gear illustrated inv -F-igs. 4-6 inclusive acts only in tension, and accord- .ingly comprises a hook 43 for engaging the ,coupling link 28.

Only one' flanged vsleeve 35a lis provided for the spring 24, at vthe farA end of the box 2.5*,.-thev other end of Athe `springs abutting directly against the box end around theA shank of the couplin hookv43. The end ofthe coupling hoo shank is secured in the sleeve'a by -a vertically"arrangedflat key 44, with cotters 4.5, 45 vin its upper'andlower ends.

' What is claimed is: 1. In combination with a mme carfloor, an inverted longitudinal metal'channel' s1ll therein, with the web thereof substantiallyl flush with the upper surface of said floor,

of longitudinal 4metal reinforcing angles aty either side of the channel secured thereto.

2'. The combination with wooden mine car flooring and' an inverted longitudinal metal channel sill therein with outward projecting flanges along its lower edges securedto said flooring, of' longitudinal metal angles befneath said anges secured thereto.

3. The combination with acar Hoor and an inverted longitudinal'metal channel sill therefor, lof longitudinal .metal draft Vsills secured to 'the channel 4sill sides to form downward extensions thereof, and a drawhead mountedlin said channel sill and se;

. cured thereto and to said draft sills.

i 4. The combination with wooden mine car flooring' and an invertedlongitudinal metal channel sill thereinwith outward projectin flanges'along its lower edges secured to sai ooring, ofy 'longitudinal metal angles heneath `said flanges secured thereto, and a drawhead mounted'in said channel sill and secured thereto and to said angles.

5. The. combination with wooden mine car iooring Yandan inverted metal channel s11l therein with its sides .secured thereto, of longitudinal metal draft sills secured to said 'flooring and extending downward below the same,iand a. drawhead mounted in said channel sill and secured thereto and to the downward extending portions of said draft sills'.

6. The combination with wooden mine car `flooring and an inverted longitudinal metal channel sill therein with outward projecting flanges along its lower edges extending beneath said flooring and secured thereto,

longitudinal metal angles beneath said ooring at either side of the channel opening secured t'o the flooring, withflanges depending therebelow, and a drawhead mounted in said channelsecured thereto and to said depending angle flanges.

7. The combinati-on with wooden mine car flooring and an inverted longitudinal metal vchannel sill therein, of longitudinal metal reinforcements secured to the channel .sill

sides to form downward extensions thereof therefor, of longitudinal metal draftsills secured to 'the' channel sill sides to form downward vextensions thereof, a drawhead mounted in said channel sill, a carry-iron yoke for the coupler mounted in the channel and secured-to said draft sills at either side,q and atransverse metal strength memberat the floor end offset downward beneath said reinforcements and the coupler. j

10. In combination with a mine car floor, a'center sill comprising an inverted longitudinal channel in said floor with the web thereof ush with the upper surface of the floor, and longitudinal .reinforcing angles secured directly to the channel at either side thereof' with one portion of said angles in` alignment with the sides vof the channel.

. 11. lIn combination with. a minecar Hoor, a center sill comprising an inverted longitudinal channel in `said floor' with the, web
